The Lancaster Watch Camera and its little sister, the ladies version, offer some of the earliest proof that spys are, indeed, among us. Ok, maybe not that, but they are a pretty neat piece of 1890’s camera engineering.
According to Bonhams’ camera expert Lionel Hughes:
It would have been very inconvenient to use as four very small catches had to be released in order to remove the glass screen and to fit a separate metal sensitised material holder for each exposure.
Constructed of engine-turned metal with nickel plating, the watch/camera expanded on its own when you opened it up. And if you could get them to work, the ladies version took 1 1/4in x 1in exposures, with the larger guy’s spy cam capturing 2in x 1 1/2in snaps.
